Pioneer SE-CL30

Pioneer's SE-CL30 are the highest-end earbuds that the company offers, and they are designed to be comfortable for long periods of time, such as during a workout or commuting. They have a unique cord design that runs behind the neck to avoid getting in the way while running or working, and they include three different sizes of earbud caps to fit different sizes of ears or to adjust the fit.

Frequency response range is wide, between 5 Hz and 23kHz, and thus the bass range is better than Pioneer's other models. The drivers are 10mm, and the cord length is 1.2 meters.
